We already know that Austin is one of the country's hottest real estate markets, and we've asked real estate experts which neighborhoods they love, but where are the best places to live in Austin?

Real estate review site Niche combined user rankings with data from the U.S. Census Bureau, Bureau of Labor and Statistics, Centers for Disease Control and Prevention, and the FBI to reveal the Best Neighborhoods to Live in America. Six hot Austin 'hoods landed among the top 50 — the most of any city in Texas.

In order to rank the top neighborhoods, Niche considered areas located within a city and with a population of at least 1,000. The site then ranked the neighborhoods using 15 different categories, each weighted depending on importance and given a different grade.

Some of the categories included:

• Higher education (number of citizens with advanced degrees)
• Cost of living
• Housing costs
• Reputation of nearby public schools
• Diversity
• Overall composite number (Niche survey responses scored on a 1-5 scale)
• Crime and safety
• Walkability

The site also examined lifestyle factors such as outdoor activities, nightlife, and average commute times.

Coming in at No. 21 in the nation is Rosedale, a Central Austin neighborhood bordered by West 38th Street on its south and North Loop Boulevard on its north. Though the area has a decidedly suburban feel, its proximity to bustling Burnet Road, hip restaurants, and lush green spaces like Ramsey Park make it the best neighborhood to live in Austin.

Just north of Rosedale is Allandale, Niche's 23rd best neighborhood in the U.S. Allandale, bordered by West 45th Street on its south, runs all the way north to West Anderson Lane. Like Rosedale, it's suburban in feel but has the amenities (great food, great parks) that Austinites love.

West Austin neighborhoods rounded out the rest of the top 50 spots (guess that diversity factor didn't mean geographically). Old West Austin came in at No. 32, while Windsor Road and Old Enfield took the 40th and 42nd spots, respectively. Only downtown Austin, which ranked No. 39 on the list, was centrally located.

In general, Texas fared quite well among the best neighborhoods in the U.S., making up 12 of the top 50. Dallas' Preston Highlands and Houston's Memorial neighborhoods both broke the top 10, coming in at No. 8 and No. 10, respectively. Other hot Dallas areas were Moss Farm-Forest Meadow (No. 14); Campbell Green (No. 28); and Lakeview Heights (No. 30).

In addition to Memorial, the other Houston 'hood to make the top 50 was University Place, which took the 20th spot.
